Joe Cartledge invented the jockstrap (or athletic supporter) in the 1920s. He played hockey, football, and rugby so his invention may have been inspired by painful, painful memories. It was marketed as “Protex.”

A parasite, in essence, is any organism that makes its living off another organism (think bed bugs, leeches, vampire fish and even mistletoe). These freeloaders have been rather successful: up to half of Earth’s 7.7 million known species are parasitic, and this lifestyle has evolved independently hundreds of times. But in a study published this week in the journal Science Advances, researchers warn that climate change could drive up to one-third of Earth’s parasite species to extinction by the year 2070.

I did not know that either. That is one HUGE sea turtle.
Dinosaur footprints exposed on a Western Australia beach prove to be part of the most abundant track sites on Earth. Some are among the largest ever found.

Brain implants that deliver electrical pulses tuned to a person’s feelings and behaviour are being tested in people for the first time. Two teams funded by the US military’s research arm, the Defense Advanced Research Projects Agency (DARPA), have begun preliminary trials of ‘closed-loop’ brain implants that use algorithms to detect patterns associated with mood disorders. These devices can shock the brain back to a healthy state without input from a physician.
The work, presented last week at the Society for Neuroscience (SfN) meeting in Washington DC, could eventually provide a way to treat severe mental illnesses that resist current therapies. It also raises thorny ethical concerns, not least because the technique could give researchers a degree of access to a person’s inner feelings in real time.
The general approach — using a brain implant to deliver electric pulses that alter neural activity — is known as deep-brain stimulation. It is used to treat movement disorders such as Parkinson’s disease, but has been less successful when tested against mood disorders. Early evidence suggested that constant stimulation of certain brain regions could ease chronic depression, but a major study involving 90 people with depression found no improvement after a year of treatment.1
The scientists behind the DARPA-funded projects say that their work might succeed where earlier attempts failed, because they have designed their brain implants specifically to treat mental illness — and to switch on only when needed. “We’ve learned a lot about the limitations of our current technology,” says Edward Chang, a neuroscientist at the University of California, San Francisco (UCSF), who is leading one of the projects.

Xpand Your Horizons is a growing online community that shares videos and other material aimed to intrigue people to think outside the box and expand the interest all around. The Xpand Your Horizons Family is sometimes shortened to "XYH" or "XYHor" here on Tumblr in our many secondary and more specific blogs. Our Family has compiled more than 60 playlists on YouTube now and has viewed every video to make sure that what is delivered is factual. If something appears questionable or the comment feedback alludes to mistakes, research is done and it is determined whether or not it's worth sharing. As of late, it is so easy to come across videos containing little to no actual research or are so heavily boggled down with opinions that you can find yourself in a battle of so-called "whits" on the internet. The Xpand Your Horizons Family doesn’t yet upload or produce any original content...yet... but we would like to make it known that We’re sharing all this contentbecause it's important to take Science seriously in a healthy and safe environment. Each playlist can be found on YouTube under the Xpand Your Horizons moniker and their specific topic(s) is/are displayed in the title, and further explanation is in their descriptions. Not all are academic inclined, some deal with pop culture as well as media. Enjoy!For more content, Click Here and experience this XYHor in its entirety!
